WALTER J. BUROHETT, OF NEVY YORK, N. Y.

AUTOMATIC BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 764,225, dated July 5, 1904.

Application filed October 9, 1903.

To (all whom it many concern.-

Be it known that I, WALTER J. liuuouu'r'r, a citizen of the United. States, residing at New York, borough of Brooklyn, county of Kings, and State of New York, have made a new and useful Invention in Automatic Bottle-Stopconstructed that when the user grasps the bottle by the neck he will simultaneously withdraw or remove the stopper and maintain it in such removed position so long as he continues to hold the bottle in this manner; fourth, to devise an automatic bottle-stopper which under normal conditions will be yieldingly held with the stopper in a closed position in the mouth of the bottle or which may, if desired, be similarly held in an open position. For a full and clear understanding of the invention, such as will enable others skilled in the art to construct and use the same, reference is had to the accompanying drawings, and to the following specification, the especial points of novelty being particularly pointed out in the claims at the end of this specification. Figure 1 is a sectional view taken through the neck and upper portion of a bottle, illustrating also in sectional view the stopper normally held in closed position; and Fig. 2 is a side elevational view thereof illustrating the stopper normally in open position. Fig. 3 is a detail developed plan view of that part of the device which constitutes the suppoft for the operative parts of the stopper and also the means for securing the same detachably to the neck of a bottle.

Referring now to the drawings in detail, in all of which like letters of reference represent like parts wherever used, B represents the neck and upper portion of a glass bottle Serial No. 176,366. (No model.)

of well-known form provided with the usual bead F near the mouth thereof.

D represents the sustainingpart of the device, the same being constructed of thin sheet metal, such as steel or case-hardened iron, and stamped in one operation in such manner as to be provided with two or more pairs of arms A A, A A, which when bent into the position shown in Figs. 1 and 2 constitute gripping means for supporting the parts detachably upon the outer portion of the neck of a bottle and near the mouth thereof, the outer ends of the arms being bent outwardly, so that the same may be slipped readily into position with the lower arms below the bead F.

T 'l constitute side lugs, which are turned upward and in an opposite direction to the arms A A, and 0 Care oblong slots, I I being openings for supporting a rivet R, which when in position pivotally supports the curvilinear operating-handle H.

J is a fulcrum-arm for the cork and its sustaining-cup secured between the lugs 'l 'l. in the slots 0 O by a screw S, the adj ustmcnt of the fulcrum-arm being when the parts are in position in the direction of the length of the bottle-neck and for the purpose of adapting the use of the parts with bottles in which the bead F is located at dill'erent distances from the mouths thereof.

O is a segmental part of a spherical cork or other flexible water-tight material lirmly secured by glue or otherwise within a coneshaped cup C, which in turn is pivotally scoured to the upper part of the fulcrum-arm l by a fulcrum-pin K.

E is a lug or car on one side of the cup C, next to the free end of the short arm of the operating-handle l-I, said lug or car being connected to the aforesaid short arm by a metal link L.

M is an operating-spring wound spirally around the rivet R between the lugs T and with its short arm bearing against the outer face of the body part 1), the long arm of said spring pressing outwardly against the inner curvilinear surface of the operating-handle H, the arrangement being such that when the parts are in the position shown in Fig. 1 the segmental stopper or cork C is firmly held in closed position. The arrangement of the adjustable fulcrum-arm J, lug E, free end of the operating-handle H, and link L is such that when the user grasps the bottle by the neck B and handle H he thereby causes the cup C, and hence the cork or stopper C, to be removed from the mouth of the bottle and to thus remain until the desired amount of the contents has been withdrawn. This arrangement of these several parts is also such that if it is desired to leave the mouth of the bottle wholly open during the time that it is being filled and without manipulating the operating-handle H the user may turn the cup C to its extreme open position, such that the action of the spring M, handle H, and link L causes the cup C to remain in the position shown in Fig. 2 or continuously open. When it is required to adapt the device for bottles having necks of different sizes, it is onlynecessary to remove the screw S, adjust the fulcrum-arm J to the proper height, and then restore the screw to its normal position. This may be ascertained after aproper trial of the adjustment, the exterior curvature of the segmental cork being such as to adapt it for the mouths of bottles having different internal diameters, as will be readily appreciable on inspection of the drawings.

I do not limit my invention to the especial details of construction illustrated in the accompanying drawings.

I believe it is broadly new with me to devise an automatic bottle-stopper having means for automatically causing the same to be held normally in a closed position, and so constructed as to adapt it to be held normally in an open position when it is desired to fill the bottle or maintain the cork or stopper permanently in such open or detached position, and my claims are generic as to these features.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. An automatic bottle-stopper consisting of gripping means for securing the same to the neck of a bottle; means for supporting the stopper adjustably with relation to the firstnamed means; in combination with an operating-handle yieldingly connected to the stopper and adapted to normally maintain it in a closed position.

2. An automatic bottle-stopper consisting of means for securing the same to the neck of a bottle; adjustable means connecting the stopper with the aforesaid means and an operating handle pivotally supported by the first-named means and operatively connected to the stopper; together with yielding means between the support and the operating-handle for maintaining the stopper in either an open or a closed position.

3. An automatic bottle-stopper consisting of a segment of a sphere, preferably of yielding material such as cork, a fulcrum-arm to which the same is pivotall y secured; a detachable support to which the fulcrum-arm is adjustably attached, said support being provided with means for gripping or grasping the neck of a bottle; in combination with an operatinghandle pivotally secured to the support and provided with yielding means for maintaining the stopper in a closed position with relation to bottles having necks of difierent diameter.

4. An automatic bottle-stopper consisting of a body part provided with yielding arms adapted to grip or grasp the neck of a bottle and side lugs having slots adapted to adjustably support a fulcrum-arm to the upper end of which is pivotally secured a cork of substantially spherical contour on one side, said cork being yieldingly connected by a link to an operating-handle which in turn is supported by the body part and is provided with yielding means as a spring for maintaining the cork in closed position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
